Meditation-related activations are modulated by the practices needed to obtain it and by the expertise: an ALE meta-analysis study.

Bottom Line: Different ALE meta-analyses were carried out.The network included clusters bilaterally in the medial gyrus, the left superior parietal lobe, the left insula and the right supramarginal gyrus (SMG).We found that frontal activation was present for short-term, as compared with long-term experience meditators, confirming that experts are better enabled to sustain attentional focus, rather recruiting the right SMG and concentrating on aspects involving disembodiment.

ABSTRACT
The brain network governing meditation has been studied using a variety of meditation practices and techniques practices eliciting different cognitive processes (e.g., silence, attention to own body, sense of joy, mantras, etc.). It is very possible that different practices of meditation are subserved by largely, if not entirely, disparate brain networks. This assumption was tested by conducting an activation likelihood estimation (ALE) meta-analysis of meditation neuroimaging studies, which assessed 150 activation foci from 24 experiments. Different ALE meta-analyses were carried out. One involved the subsets of studies involving meditation induced through exercising focused attention (FA). The network included clusters bilaterally in the medial gyrus, the left superior parietal lobe, the left insula and the right supramarginal gyrus (SMG). A second analysis addressed the studies involving meditation states induced by chanting or by repetition of words or phrases, known as "mantra." This type of practice elicited a cluster of activity in the right SMG, the SMA bilaterally and the left postcentral gyrus. Furthermore, the last analyses addressed the effect of meditation experience (i.e., short- vs. long-term meditators). We found that frontal activation was present for short-term, as compared with long-term experience meditators, confirming that experts are better enabled to sustain attentional focus, rather recruiting the right SMG and concentrating on aspects involving disembodiment.

Common network of activations (A) and deactivations (B) underlying meditation are displayed on a rendered template brain provided by spm5 and on axial slices of the MNI single subject template, with activations (in orange) and deactivations (in blue) overlaid on the same template (C). Relative increases in neural activity associated with meditation induced trough focused attention (D) and through mantra recitation (E) are displayed on a rendered template brain provided by spm5 and on axial slices of the MNI single subject template, with FA related activations (orange) and mantra recitation related activations (blue) overlaid on the same template (F). All activations are significant at p < 0.05 corrected for multiple comparisons using the false discovery rate (FDR). Color bas show ALE value.

Mentions: The 10 activation clusters resulting from the meta-analysis of all the included studies comprised bilaterally the superior medial gyrus (clusters 1 and 6), more superiorly the left superior medial gyrus (cluster 5), medially the left paracentral lobule (cluster 10) and the right supplementary motor area (SMA) (hereafter SMA, clusters 7 and 9), the left superior (Area 7a, cluster 3) and inferior parietal lobe (Area 2, extending to area 4p and 3b, cluster 4), and left insula (cluster 8). Right lateralized activation was found in the supramarginal gyrus (SMG) (cluster 2) (Table 2 and Figure 1).
